DEMOUNTAB LE RIM VEEIC LE-VVHEELS'.

To all Q/Z]! 0m it may concern Be it known that L'Jomv L. Wensrnn, acitizen of the United States; residing at Chicag in the county ofwCookand State ot'lllinois, have invented certain new and useful Improvementsin Demountalole Rims for Vehicle-Wheels; and I do hereby declare thefollowing to be a full, clear and exact description of the invention,such as will enable others skilled inthe art to which it appertains tomake and use the same, reference being had to the accompanying drawlngs,and to the letters and figures of reference marked-thereon, which form apart of this Is iiecificatiou.

This invention relates to new and useful improvements in devices forremoving and replacing tires upon vehicle riinsand coinprises adernountable rim of this nature having various details of constructionand combinations and arrangements of parts which will be hereinafterfully described,

shown in the accompanying drawings and then spec fically defined in theappendedclaims.

I illustrate my invention in the accompanyingi drawings, in which 1-Figure 1 is a sideeleva tion of a vehicle wheel showing theapplicationabii my invention thereto. Fig. 2 is'an enlarged detail inelevatiori or aportion of the rim of a wheel and tire, part being shownn section to better illustrate features of the 1m ention;

Fig. dis a sectional view on line 3.-3 of Fig. 2. Fig. 4 1s 'a'detailperspective view of parts of' thein'vention. Fi 5 is a detailperspective viewof the locking nieans,-and

.Fig) 6 a view showingparts ot' the rim sections. i A I v Reference now.being' had to the details of the, drawings'bynumeral; l'designates atelly of the wheel and 2 the spokes and a pneumatic tire which. isfastened to the band 4t which has its inner surface 5 inclined,

as shown clearly in Fig. 3 of the drawings.

' and is apertured at 6 for the reception of the locking bolt 7 whichlatter is provided with a head 8 and has a spiral thread 9 formed uponits circumference.

- A fixed rim, designated by numeral 10, is fastened to the wheel felly1 in any suitable manner and at intervals in said felly 1 are formedrecesses 11 in which the socket members'12' are seated andwhich are heldin place by means of bolts 13 passing through the telly and engaged bynuts 14 of said.

Specification of LettersPatent.

Said arm 21 has a lug gPatcntcd dept. 22, initial.

serves to hold the lug 18 in the notch 17 and the other end of the leveris bent at an all-- gle and extends through an aperture 23*. 22 at oneend which is apertnred as at 23 for'the reception of a kev 24, a detailof which is shown in'Fig. 5 oi the drawings. The bore of the socket meinbenlQ has a spiral groove therein adapted to he engaged by the threacl9and said colt 7 is adapted, as the bolt is moved longitudinally, to movethrough the registering apertures formed in the band 4 and fined riin10,. ilSLSllOWll in Figs. 2 and 3 of the drawings.

. Upon referenceto Fig. 4, it will be noted that the band .4: isprovided with a lug 25' upon its: inner circumference and the oppositeedges of which are inclined and adapted to'e'ngage a similar shapedrecess 26 formed in the outer inclined surface of the fixed run 10 andwhich serves to hold the two from turning independent one of the other.

In Fig. l oi. the drawings, I have shown two of said projections 25arranged diametrically opposite each other and it will he noted .thattheprojections 25 are slightly wider than the depth of the recess, servingto hold the band l spaced apart a slight distance from the folly band,while lugs or projections 27 project about the inner marginal edge oftheapertur s'il and beyond the inner circumference of the band l, thusforming four PIOJCCUODS for holding the band and fixed rim spaced apartto prevent the latter'binding togethertoo tightly which would interferewith their ready removal one from the other. 7

In applying and removing the tire with its hand 4, the latter is placedabout the inclined circumference of the fixed riin 10 and, when theapertures in the band and fixed rim are in registration, the arms 21 maybe swung from the position shown in dotted lines in Fig. 2 in which thebolt is at its farthest outer throw to the position shown in solid linesin the same figure, which will cause the bolt" to be thrown for wardthrough the registering apertures in the band and fixed ri'm, thussecurely holding the latter in' a locked relation. As the.

"lever comes in" siich'position that the lug 18 comes intoregistrationwith the notch 17, the spring 18 will throw said lug into .said notchand't'hold the. lever from turning.

"bolt toturn and assume theposition shown in: dotted lines in Fig. 2,after 'which .the band section with the tire attached may be readilyremoved. It will be noted from the constructio shown and described thata simple and efficient means is afforded whereby a tire with the'bandand fixed rim may be easily and quickly applied to or removed from thefelly of a wheeel.

What I- claim to be new is 1. Ademountable rim forivehicle wheelscomprising a band and a fixed rim, the latter adapted to be fastened tothe felly of the wheel and havin its outer circumferenoe tapering and te other designed to receive-a tire and tapering upon its innercircumference, the. said band and fixed rim adapted to telescope .each'other, a bolt mounted in the felly and adapted to engage registeringapertures in the fixed-rim and band, the head of the bolt having an arm,

a lever pivotally mounted upon said arm and having a lug projectingtherefrom for engagement with the felly, said arm being provided with anapertured lugdesigned to receive a key, asset forth.

2. A demountable rim for vehicle wheels 1 comprising two rim sections,one adapted to-be fastened to the wheel rim and having 1ts outercircumference tapering and tlie other designed to receive a tire andtaperingflupon its inner circumference, the two band "sections" adaptedto telescope each other, ,.a socket member mounted in a recess in thewheel telly and provided with sp1r'al -grooveupon its inner wall, a boltengaging said groove and adapted, as the bolt is rotated, to movethrough'registering- "apertures in the rim sections, said socket memberhaving a lateral projection with .a notch therein, the head "of the boltbeing provided with an arm, a pivotal spring-pressed lever mounted uponsaid arm and having a big for engagement with said notch, as set forth.

A demountable rim for vehicle wheels comprising two rim sections, oneadapted to be fastened to the wheel rim and having its outercircumference tapering and the other designed-to receive a tire andtaperlng upon its inner circumference, the two .band sections adapted totelescope each other, a. socket member mounted in a recess in the wheelrim andprovided with a spiral groove upon its'inner wall, a boltengaging saidgroore' and adapted, as the bolt is rotated, to movethrough registering apertures in the rim sections, said socket memberhaving a lateral projection with a notch therein, the head of the boltbeing provided with an arm, said arm having a recess in its inner face,a pivotally mounted spring-pressedrlever in said recess having a. lugfor engagement with said notch, one end- 0f the lever extending throughan aperture in the wall of the recess and the end of the arm terminatingin a lug which is apertured for the reception of a key, one end of whichis adapted, as the key is turned, to bear against the end of the leverprojecting through said aperture to causev the lever to be tilted, asset forth.
